Global Warming

Answer

Global warming is the gradual increase in Earth's average temperature due to excessive greenhouse gases in the atmosphere. These gases trap heat from the sun and prevent it from escaping back to space…

Answer

The five main greenhouse gases are: 1. Carbon dioxide (CO₂), 2. Nitrogen dioxide (NO₂), 3. Chlorofluorocarbons (CFCs), 4. Hydrocarbons, 5. Methane (CH₄). These are also called Earth heating gases.

Answer

The greenhouse effect is a natural process where greenhouse gases trap heat in Earth's atmosphere. It is important because it helps maintain Earth's temperature at a level suitable for life. However, …

Answer

The glass covered with a bowl showed higher temperature. This is because the bowl acted like greenhouse gases, trapping heat inside and preventing it from escaping. This demonstrates how greenhouse ga…

Answer

The primary sources are: 1. Factories and chemical industries, 2. Human activities, 3. Air conditioners and refrigerators (CFCs), 4. Burning of household wastes, 5. Burning of plastic materials.

Answer

CFCs (Chlorofluorocarbons) are greenhouse gases used in air conditioners and refrigerators. When these appliances leak or are disposed of improperly, CFCs are released into the atmosphere where they t…

Answer

Ice melts faster in the covered glass because the cover traps heat, creating a warmer environment inside. This simulates how greenhouse gases trap heat in Earth's atmosphere, causing faster melting of…

Answer

Vermicomposting is the process of converting household waste into manure using earthworms. It helps reduce global warming by preventing the burning of household waste, which would otherwise release gr…
